Infected cutaneous ulcers from diabetic rats with and were treated with spray formulations containing green silver nanoparticles (GS), chemical silver nanoparticles (CS), or pomegranate peel extract (PS). After wound development and infection, the treatments were performed twice per day for 14 days. The wound healing was analyzed on days 2, 7, and 14 through the determination of CFUs, inflammatory infiltrate, angiogenesis, fibroplasia, myeloperoxidase, and collagen determination. Expressive improvement in wound healing was noted using both silver nanoparticles for 7 days. All the treatments were superior to controls and promoted significant reduction after 14 days. CS presented better anti-inflammatory results, and GS and CS the highest number of fibroblasts. Despite the techniques' limitations, GS and CS demonstrated considerable potential for managing infected wounds, especially considering no early strategies prior to the drugs, such as the debridement of these wounds, were included.
用含有绿色银纳米颗粒(GS)、化学银纳米颗粒(CS)或石榴皮提取物(PS)的喷雾制剂治疗患有[具体情况未明确]的糖尿病大鼠的感染性皮肤溃疡。伤口形成并感染后,每天进行两次治疗,持续14天。在第2天、第7天和第14天通过测定菌落形成单位、炎性浸润、血管生成、纤维增生、髓过氧化物酶和胶原蛋白来分析伤口愈合情况。使用两种银纳米颗粒7天时,伤口愈合有明显改善。所有治疗均优于对照组,14天后炎症显著减轻。CS表现出更好的抗炎效果,GS和CS的成纤维细胞数量最多。尽管这些技术存在局限性,但GS和CS在处理感染伤口方面显示出相当大的潜力,特别是考虑到在药物治疗之前没有包括早期策略,如这些伤口的清创术。
